Relationship of interleukin-6-572C/G promoter polymorphism and serum levels to post-percutaneous coronary intervention restenosis.

Background: It has been recently reported that inflammatory mechanisms play an important role in in-stent restenosis (ISR) processes. Inflammatory factors after percutaneous coronary intervention (PCI) for dynamic monitoring can probably predict ISR. Functional polymorphisms in the promoter region of genes coding for inflammatory factors might be important for determining the magnitude of the inflammatory response.

[Impact of proton pump inhibitor omeprazole on the antiplatelet effect of clopidogrel in individuals with various CYP2C19*2 genotypes].

Objective: To investigate the impact of omeprazole on platelet response to clopidogrel and the effect of polymorphisms of CYP2C19 on the antiplatelet effect of clopidogrel.

Methods: Platelet aggregation (PA) was assessed before 300 mg aspirin plus 300 mg loading dose of clopidogrel and after 300 mg aspirin plus 75 mg maintenance dose of clopidogrel 7 days later in 414 patients with acute coronary syndrome who have undergone percutaneous coronary intervention (PCI). Thereafter, gastric mucosal protective drugs were given (omeprazolem 20 mg, n=224 or cimetidine 800 mg, n=190).

[Association between -14 bp and ZNF polymorphisms of ABCA1 gene promoter and high density lipoprotein cholesterol level and cardiovascular disease].

Objective: To investigate the association between polymorphisms at -14 bp and zinc finger protein(ZNF) sites of ATP-binding cassette transporter A1 (ABCA1) gene promotor and high density lipoprotein-cholesterol (HDL-C) level and coronary heart disease (CHD).

Methods: Polymorphisms of Bme13901 restriction site at -14 bp and an insertion/deletion site of ACCCC in variable number of tandem repeats-zinc finger protein(VNTR-ZNF) of ABCA1 gene were detected using PCR in 260 CHD patients and 220 healthy subjects from a Chinese population in Tianjin.

Results: CT genotype was most common in both groups with no differences found in between (P> 0.

[Improvement of cardiac function by recombinant adenovirus Ad-hBNP in rats with chronic heart failure].

Objective: To evaluate the therapeutic effect of hBNP on rats with chronic heart failure (CHF).

Methods: Thirty CHF rats defined by echocardiography at 12 weeks post abdominal aortic constriction were randomly divided into Ad-hBNP group (2.5 × 10(10) VP/ml NS Ad-hBNP 1 ml/week × 4, n = 14), Ad-Track group (n = 8), placebo group (NS, n = 8), 10 sham-operated rats served as control group.

[Relationship of interleukin-10 gene polymorphism with restenosis after percutaneous coronary intervention in Chinese].

Objective: To investigate the relationship of interleukin-10 gene (IL-10) polymorphism and the serum IL-10 level with restenosis after percutaneous coronary intervention (PCI) in Tianjin Chinese Han population and study the effect of IL-10 gene polymorphism on serum IL-10 level.

Methods: Four hundred and thirty-seven patients who successfully underwent PCI with a follow-up angiography were divided into a restenosis group (n = 166) and non-restenosis group (n = 271). The IL-10 gene promoter polymorphism at position -592 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.

[Expression of angiotensin II receptor subtypes in atrial fibrillation underlying rheumatic heart disease].

Objective: To examine the expression of angiotensin II (Ang II) receptor subtypes in human left and right atrial tissue in atrial fibrillation underlying rheumatic heart disease.

Methods: Atrial tissue samples were obtained from 39 patients with rheumatic heart disease, 25 with atrial fibrillation (AF) and 14 with sinus rhythm(SR) during open heart surgery. AT1 and AT2 mRNA levels were measured with semi-quantitative reverse transcription polymerase chain reaction techniques.

[The effect of gene polymorphism in promoter and intron 1 on human ApoA I expression].

Objective: To construct pGL2-ApoA I luciferase reporter vector containing ApoA I gene regulation area, and to investigate the effect of G --> A and C --> T substitution in ApoA I promoter -75 bp and intron 1 +83 bp region respectively on ApoA I gene expression.

Methods: Human chromosome DNA fragments containing ApoA I gene were amplified by PCR, and the DNA fragments consisting of ApoA I AA/CC, GG/TT and GG/CC genetypes were selected separately, then pUC vector including above three different DNA fragments was constructed. After digesting pUC vector with Sac I and Bgl II, ligate the different DNA fragments to basic pGL2 vector that containing luciferase reporter gene.
